ARTHUR E. WHITNEY, OF YVINGHESTER, MASSACHUSETTS HIDE-FL-ESHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 473,039, dated April 19, 1892.

7 Application filed November 14-, 1891. Serial No. 111,895. (No model.)

To aZZ whom, it may concern:

Be it known that I, ARTHUR E. WHITNEY, of \Vinchester, in the county of Middlesex and State of Massachusetts, have invented certain new and usefullmprovements in Hide- Fleshing Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to liide-fleshing machines; and it consists in certain novel features of construction, arrangement, and com-l bination of parts, which will be readily understood by reference to the description of the drawings and to the claims hereinafter given, and inwhich my invention is clearly pointed out.

Figure 1 of the drawingsis an end elevation of a machine embodying my invention. Fig. 2 is a vertical sectional elevation, the cutting plane being on line 1 1 on Fig. 4, looking toward the right of said figure. Fig. 3 is a partial sectional elevation of the end opposite to that shown in Fig. 1, drawn to an enlarged scale. Fig. 4 is an elevation of the back side of the machine. Fig, 5 is a partial sectional elevation of one end of the machine, the cutting plane being on line 2 2 on Fig. 3 and drawn to the same scale as Fig. 3.

In the drawings, A A are the two end frames of the machine, connected together by the tie-girts B, B, and B and having their upper ends slotted to receive the boxes 0 O, which rest upon and are supported by the inner ends of' the levers a, pivoted at a and adjustable about said pivotal connection by means of the set-screws b b to adjust said boxes and the feed-roll D, mounted therein, to the desired elevation, said roll being pressed down upon said supporting-lever by means of springs c,

contained-in the casing c and adjustable to regulate their tensions by the set-screws 0 substantially in the same manner as described in the Letters Patent, No. 367,257, granted to mounted in fixed bearings in the framesA A,

as shown in Figs. 1 and 1.

F is the bed-roll, having its periphery covered with a sleeve or envelope 6, of rubber or other elastic material, and mounted in bearings in the boxes ff, fitted to the forked upper ends of the two radius-arms G G, the lower ends of which are pivoted to the crossbars'A' of the frames A, as shown in Figs. 3 and. 5.

H is a toggle-link pivoted at one end to a A, in which it is movable toward and from the center of the machine, it being pressed against the abutment at the inner end of said socket and toward the center of the machine by the spring h, inclosed in the housing J, the ten- 'sion of said spring being adjustable by the set-screw J ,acting upon the piston 9 said set-sdrew being clamped in its adjusted position by the check-nut J K K are two treadle-levers pivoted one to the inside of each of the frames A and connected together at'their outer ends by the treadle board K, as shown. Each of the treadle-levers K has adj ustablysecured in its inner end the laterally-projecting arm'K to the lower end of which is pivoted the lower end of a treadle-rod I, as shown in Figs. 1 and 4:. A set screw 1 is fitted to each frame A in such a position and manner as to serve as an adjustable stop to limit the inward movement of the radius-arms G G.

L L are two levers mounted upon the inner ends of the fulcrum-pins of the radius-arms G G and provided at the end of their short arms with laterally-projecting arms orlugs i, with which the front sides of the radius-arms G come in contact to raise the long arms of said lever L to the positions shown in full lines in Fig. 2, when the bed-roll is moved away from the fieshing-cylinder, as shown in Fig. 2. The long arms of the levers L have adj ustably mounted thereon the counterweights' L, which partially counterbalance the weight of the bed-roll when in itsretracted position, and thus reduce the amount of power necessary to be applied to the treadle to move said bed-roll into contact with the feed-roll and fleshing-cylinder when the skin to be fleshed has been placed thereon.

M M are two arms pivoted one to the inside of each frame Av near its back or rearedge and projecting toward the frontiof. the ma: chine to a point above the rear end of the treadle-lever K, and each of said arms has secured thereon the upwardly projecting arm j in the same vertical plane as the long arm of the lever L, and is also provided with the lugj, which engages with the inner edge of the rear upright of the frame A to limit the downward movement of the inner end of the arm M.

Each of the front sides of the upper forked ends of the radius-arms G has secured thereto by any suitable means a cushion is, of rubber or oth er yielding material, which comes in contact with the shoulder on theframe A to arrest the outward movement of the bed-roll with the minimum of shock or jar to the machine.

Rotary'motionis imparted to the fleshingcylinder by means of the belt Z, leading from, any suitable counter-shaft to the pulley Z on the shaft of said cylinder. The opposite end ofsaidshaft has secured thereon-the broadfaced pulley Z from which the belt m leads to and around the loose pulley m or the tightpulley m mounted upon a stud set in the plate A secured to the left-hand frame A. The tight pulley m has formed upon orsecured to its hubthe pinion n, (shown in dotted lines in Fig. 1,) which meshes into and imparts motion to-the spur gear-wheel N, also mounted upon a stud set in the plate A and having connected therewith the pinion n, which meshesinto and imparts motion to'the spur gear-wheel N, which has secured to its inner face the sprocket-Wheel O. (Shown in dotted lines in Fig. 1.) The gear-wheel N is mounted upon the outer end of the fulcrumpin, which connects the left-hand radius-arm G to the frame A and meshes into and imparts motionto the spur gear-wheel N mounted upon a stud set in the plate A secured to the outer face of the left-hand frame A, and having secured thereto the sprocket-wheel 0. (Shown in Figs. 1 and 4.) A chain belt P connects the sprocket-wheel O with thesprocket-wheel P on the left-hand end of the bedroll F, and a similar chain belt Q connects the sprock et-wheel O with the sprocket-wheel Q on the left-hand end of the feed-roll D,,

said chain belt being sufficiently slack to permit the necessary adjustment of the feedroll-D.

S-is a shipper rod or bar mounted in bear- I ings in the stand R, bolted toand projecting outward from the left-handframe A, and has secured thereon the shipper-fingers 0 0 and the pendent arm 13, with which the forked upper end of the three-armed lever T engages, as-shown. The lever T is pivoted to cars 19 on the plate A and has a pin 0" set in the end of thearm 0 to enter the slot 0 in the rod- 19 the lower-end of which is pivoted to one of the treadle-levers K'and has suspended from the end of the arm 0 the counter-weight WV, all as shown-in Fig. 5.

,hide so as to injure it.

If desired, plain pulleys may be substituted for thesprocket-wheels O, 0-, P, and Q and ordinary belts for the chain belts P and Q without affecting the principles of my invention.

The blades of the fleshing cylinder are ground concentric to the axis of said cylinder, and I. have found by practical test that a cylinder having a large number of spirallya-rranged blades arranged as shown and ground as described willspread out the hide upon the bed-roll and remove the surplus flesh without the intervention of a spreadingcylinder distinct from the fieshing-cylinder, except when the cylinder is acting upon the irregular skirts of the hide, which are liable to be at one side or the other of the center of the length of the fleshing-cylinder, in which case the action of the spiral blades tends to bend said projecting portion of the hide. too

far to one side or the other, thus forming a fold therein, and then the blade will cut the To obviate this difficulty, I mount a stiff rocker-shaft U in bearings in the frames A, secure tosaid shaft a steel plate 1 of a length equal to the lengths of the bed-roll and fleshing-cylinder, said shaft and plate being so arranged that the upper portion of one side will pressupon the hide being acted upon and hold it hard against the surface of the bed-roll when said roll is moved into position to bring the'hide placed thereon into contactwvith the blades of the fleshing-cylinder, and thus prevent the irregular projecting portions of the hide being thrown to one side and injured by the blades of the fleshing cylinde1x r The shaft U has secured to one end thereof the-lever V, from the free or movable end serves to hold the lever V in contact wi-t-hthe stop screw 7' until the bed-roll is brought into contact with the upper'edgeof the plate, when said plate will be moved about the axis of the shaft U a limited distance, liftingthe movable end of the-l'e verV and the weight V'.

The shaft U andplater areshown best in Figs. 2 and 3, and partly in. Fig, 4, where a great portion of these parts are broken away to show the bed-roll beyond; The lever V and Weight V are shown in Figs, 3- and 4:.

The operation of my invention isasfollows:

The parts being in the positions-shown in-the drawings, and power being applied to the 'fleshing-cy-linder E to rotate-it at a-high rate lines in Fig. 2, which can be done withthe exercise of asmall amount of power onaccount of which is suspended the weight V, which IIO of the counterbalance-weight L, and causes the toggle H H to be nearly straightened, the bed-roll to he moved intothe position shown in dotted lines in Fig. 3, so as to cause the hide placed thereon to come in contact with the upper part of the plate 1 and with the blades of the cylinder E. The first part of the movement of the treadle-board and the forward movement of the bed-roll from its state of rest is further facilitated by the fact that the leverage of the short arms of the treadle-levers is much greater at the start than during the last part of the movement of said treadle, when the toggle is in its most advantageous position for exerting power. The last part of the downward movement of the treadleboard ca uses the belt m to be shipped from the loose pulley m upon the tight pulley m by the upper end of the slot 0 in the rod 13 coming in contact with the pin 0' in the arm 0 of the lever T, and at the same time the rear ends of the treadle-levers K K come in contact with and lift the free ends of the arms M M into the position indicated by dotted lines in Fig. 2, whereby the levers L are arrested in their descent or raised to the position shown in dotted lines in Figs. 2 and 3, with their late rally-proj ectin g lugs or arms 1 removed from contact with the arms G, when the weights L will serve to somewhat more than counterbalance the treadle-board, so that when the operators foot is removed therefrom the treadle will automatically assume the position shown in full lines and the'arms G G and the bed-roll will assume the position shown in full lines in Figs. 1, 2, and 3.
